The EV charger cloud security checklist
The March 2026 ransomware attack on charger manufacturer ELECQ exposed a pattern we see across the sector: cloud security treated as an afterthought. Customer names, addresses and contact details were compromised on cloud infrastructure while the chargers themselves were unaffected. We built this checklist to help teams find the gaps before an attacker does.
It is a structured starting point for an informed conversation about your security posture, spanning data architecture, remote access, communications security, firmware integrity, incident response and vendor procurement. It runs in your browser: tick each item and the readiness score updates as you go.
What it covers
Runs in your browser
- 24 items across data architecture, remote access, communications, firmware and incident response
- Mapped to UK GDPR, the Smart Charge Points Regulations 2021, OCPP 2.0.1 and ETSI EN 303 645
- Scoring bands that turn a self assessment into a clear next step
- A procurement section written for charge point operators and local authorities evaluating vendors. See public charging networks.
Provided for information only. It does not constitute legal, regulatory or security advice, and you should seek professional guidance on your obligations under UK GDPR and the Smart Charge Points Regulations 2021.
The library
We are rebuilding our interactive tools on the new platform and adding new ones. Everything is free. Where a tool is still in development, ask to be notified and we will let you know when it ships.
EV Charging Security · Available now
EV charger cloud security checklist
A 24 point self assessment covering data segregation, remote access, TLS and certificate hygiene, signed firmware updates and incident response.
Open the toolStandards Readiness · Available now
EV charging standards auditor
An interactive readiness check for the 2026 UK regulatory changes - ISO 15118, OCPP, and the Smart Charge Point and Public Charge Point Regulations - with a critical standards timeline and a section-by-section audit.
Open the toolProtocol Choice · Available now
OCPP migration decision matrix
OCPP 1.6, 2.0.1 and 2.1 side by side across security, device model, smart charging, ISO 15118 Plug & Charge and bidirectional power - with a straight recommendation on which to build on and how to migrate.
Open the toolSite Planning · Coming soon
Site capacity check
Estimate how many chargers a supply will carry before you commission a design, and see where dynamic local load balancing lets you add capacity without a costly grid connection upgrade.
Open the toolStandards Readiness · In development
ISO 15118 & AFIR readiness check
A guided assessment of where your hardware and software roadmap sits against ISO 15118-20, TLS 1.3 with mutual authentication, and Plug & Charge PKI ahead of the EU AFIR deadline for new Mode 3 chargers.
Ask to be notifiedCost Modelling · Planned
Charger development cost & time estimator
A quick way to gauge the development effort of a bespoke charge point - and how much a modular technology approach reduces time, cost and risk versus building from scratch.
Ask to be notifiedLooking for something specific? Several of these started as a request. Also in resources: the EV charging glossary and our insights.
Why we build them
Grounded in practice
Drawn from charging systems built since 2010, including a fully integrated vehicle to grid project.
Regulation aware
Mapped to the standards that actually govern UK and EU charge points, rather than generic best practice.
Straight to a conversation
When a tool surfaces a gap, we will review your OCPP stack, cloud architecture and firmware security with you.

Start with the constraint
If a tool has flagged something, or you are weighing up a design, a migration or a compliance question, describe it and you will hear from an engineer.
